Cooper Bussmann GDA-200MA Fast-acting Cartridge Fuse 0.2A

Product Description

The COOPER BUSSMANN GDA-200MA is a ceramic-body, fast-acting cartridge fuse rated at 0.2 amps. It is engineered for overcurrent protection in control circuits, instrumentation panels, and sensitive electronic equipment found across HVAC, electrical, and industrial trade applications. The mini cartridge form factor measures 20 mm in overall length and 5 mm in diameter, fitting standard 5x20 mm fuse holders. Its fast-acting response characteristic means it opens quickly on overload, protecting downstream components from sustained fault current. Installation is performed by qualified electricians and controls technicians working on low-current circuit protection applications.

This fuse is suited for use in residential and light commercial control boards, instrumentation equipment, and electronic assemblies where a 5x20 mm fast-acting fuse is specified. It is commonly found in HVAC control panels, test equipment, and precision electrical enclosures requiring reliable overcurrent protection at low amperage thresholds. The ceramic body construction provides added arc suppression compared to glass-body alternatives, making it appropriate for circuits where fault energy must be managed safely.

Key Features

• Fast-acting fuse timing for immediate overcurrent response on sensitive circuits
• Ceramic cartridge body for superior arc suppression and thermal durability
• Mini 5x20 mm form factor fits standard industry fuse holders
• Rated at 0.2 amps for precision low-current circuit protection
• RoHS compliant construction
• Recognized under multiple international standards including UL, CSA, IEC 60127-2, and CCC

Compatibility

Designed as a direct-fit replacement for standard 5x20 mm fast-acting cartridge fuse positions in control boards, instrumentation panels, and electronic equipment requiring a 0.2 amp fast-acting ceramic fuse.

Installation Notes

Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse amperage and timing rating exactly match the original specification before installation. Use an appropriately rated fuse puller for 5x20 mm holders to avoid damage to the fuse or holder contacts. Confirm all NEC or applicable local electrical code requirements are met before returning the circuit to service.
